Oakland receives minor league infielder Max Schrock in return for lefty and cash

Rzepczynski was originally acquired from the Padres with Yonder Alonso for Drew Pomeranz, Jose Torres, and Jabari Blash, on Dec. 2, 2015. The 30-year-old lefty has gone 1-0 with a 3.03 ERA in 55 games for Oakland this season, all out of the bullpen.

Over his last 15 games, he's allowed just one earned run in 8.1 innings for a 1.08 ERA during that stretch. On the season, he leads all Major Leaguers with 53 inherited runners, and is tied for the Major League lead in inherited runners scored with 18.

Schrock began the season with Single-A Hagerstown, posting a .326 average in 67 games before being promoted to Single-A Advanced Potomac on June 27. He has hit a combined .333 with 31 doubles, two triples, nine home runs, and 68 RBI in 120 games between the two levels.

This year, the 5-8, 180-pound left-handed hitter has hit a combined .352 with eight of his nine home runs against right-handers and .283 against lefties. He has appeared in 100 games at second base and two at shortstop.

The 21-year-old was originally drafted in the 28th round of the 2012 draft by Arizona but did not sign. He played three seasons at the University of South Carolina, culminating in a Second Team All-SEC selection his junior year. In 2015, he was selected in the 13th round of the MLB Draft by Washington.
